  2. Purpose • Provide information about citizens’ perceptions of priorities for transportation planning in the Missoula area. • One of several important information sources that will be used to develop Missoula’s long-range transportation plan.

  3. Methods- 1 • How? • Computer-assisted telephone interview • Random-digit dial • Kish table within household selection • Whom? • Age 18 + • Live in Missoula 2.5 PM area • Households with landline phones • When? • 1/22/08 through 2/10/08 (Cold Weather) • How was it tested? • Full pilot test • Where do respondents live? • Residences geo-coded

  4. Methods - 2 • How Many? • 430 completed interviews • Sampling Error Rate? • 5% (+/-) • Response Rate? • 51.7% • AAPOR RR3 (2006) • Weighted Data? • By 2006 U.S. Census Age and Sex for Missoula County

  5. Methods - 3  The difference between estimates for Missoula County is significant at the .05 level.

  6. Public’s Transportation Priorities • Top 3 • Improving safety at known high accident locations, • Minimizing the negative impacts of future transportation projects on natural features like rivers and wildlife habitat, and • Reducing traffic congestion in corridors that are currently severely congested. • Near the Bottom • Reducing the number of miles driven by single-occupant vehicles.

  7. Four Possible System Improvements: A Closer Examination • Improve bicycle or pedestrian facilities • Increase or improve public transit • Expand road capacity • Improve safety for drivers, passengers, bicyclists, and pedestrians.

  8. What action would improvetransportation in the Missoula Valley more? • Rank all four actions • Head-to-head comparisons, example: 1. Would improving bicycle and pedestrian facilities, or 2. Providing more or improved public transit services improve transportation more?

  9. Summary Observations • Safety, environmental issues, and traffic congestion are key public opinion factors. • Many respondents view expanding road capacity as a way to reduce traffic congestion and improve safety. • Many respondents thought of the phrase, “expand road capacity,” in a broad sense. • Be very careful when attempting to enforce pre-conceived ideas of logical consistency on citizens’ responses.
